Dell EMC Celerra (Discontinued)

It's perfect for a large environment with a small IT Staff. It is a great solution that is already built into the VNX product and provides the best way, in my opinion, to quickly create a network file share environment. I hesitate to say that many negative things about it but it can be difficult to back up. In an all virtual environment with virtual backup software, it is near impossible to back up without a separate solution. We are a Veeam customer and cannot use Veeam to backup the NAS files in a fast reliable way so we rely on a separate backup software just to back up the NAS files.

EMC Isilon Scale-Out NAS

EMC Isilon Scale-Out NAS is well suited for larger files (greater the 128 Kb) and where you need to have everything in one common name space. Where it is less appropriate is for many small files (millions of files less than 128 Kb in size) - this causes the protection level to becoming mirroring, which will cost more space.

Pros

Dell EMC Celerra (Discontinued)

  • The downtime has been zero since implementing the solution 6 years ago.
  • It provides a safe effective way to provide network storage for all users with an easy interface to provide user rights.
  • The read/write speeds are much faster than Windows.
  • It does not rely on a separate server for performance. This is due to the fact that it is not subject to Windows updates or memory/processor constraints of a Windows based OS.

EMC Isilon Scale-Out NAS

  • Isilon NAS scales up well and node replacement is easy. You can replace a node by simply adding a new node and evacuating the node that you want to retire.
  • If the file system layout is designed and executed properly it is an excellent SMB platform with the flexibility to adjust to different share structures. Make sure to take the time to fully understand the AD integration and best practices for share and NTFS permissions management.
  • Node redundancy allows for most upgrades to be installed and applied with rolling node reboots allowing the file systems to stay available throughout the process of applying updates.
  • Native replication is excellent. Jobs complete quickly and we rarely have any replication issues with our Isilon to Isilon replication.

Cons

Dell EMC Celerra (Discontinued)

  • Reporting is not very easy to figure out.
  • It requires some training of admins to figure out the best way to manage the shares, quotas, and permissions.
  • It's difficult to migrate to/from when implementing. Short of using copy based tools and scripting there is no other way to move on old file server to the NAS or to move files out of the NAS onto a Windows based server share.

EMC Isilon Scale-Out NAS

  • OneFS block size is somewhere around 128kb stripe unit while most of our tif image files are around 50kb so our logical vs. physical storage is far apart. This caused extra capacity to be needed. I'd like to see the minimum block size to be smaller or initially adjustable depending on user data type.
  • This may just be a training issue, but it's confusing looking at "free" space available when I have a file share mapped to Windows vs. what OneFS states for available free space as they do not match.
  • We noticed that after adding a new node to an existing cluster in production that we had to adjust the networking config in OneFS to allow for another dhcp address so the new node could get an IP address. Normally this wouldn't matter, but it did have a nasty side effect where the SMB service failed after changing the network config which caused a system wide outage since we mostly use SMB protocol. Once the SMB service was restarted via ssh, we were back in business and it was working again.

Alternatives Considered

Dell EMC Celerra (Discontinued)

They both provide the same functionality and, while Windows files systems in a Virtual setting are much easier to backup, Celerra is much more reliable. The Celerra servers do not require frequent rebooting, patching, or planned downtime like a Windows file system. In the event a patch or update is required for the Celerra there are typically multiple server points to provide a second pathway and prevent downtime. The boot times for a large Windows file share server is much longer than that of the EMC solution as well. There are many tools for a Windows based server, both by Microsoft and third party software vendors, and very few tools that provide the same functions for the Celerra. There are still plenty of tools available that can run on a Windows machine to run against the Celerra though. The Celerra will require more than basic file server skills and little to no Windows file server skill sets will apply to the administration of the Celerra, outside of the typical sharing and permissions.

EMC Isilon Scale-Out NAS

Isilon is immensely more scalable than Celerra and gave us better control over snapshots and replication. The addition of global deduplication provides a huge space savings benefit as well.

Return on Investment

Dell EMC Celerra (Discontinued)

  • NO WINDOWS UPDATES! This has been a huge positive impact for our environment.
  • The administration is very simple, once you have properly learned how to use it.
  • The backups and user file auditing have made things difficult. The fact that we still use it with these two difficulties speaks to how much we still prefer it to a Windows based file system.

EMC Isilon Scale-Out NAS

  • Isilon provides very high value for money
  • Matches the performance and storage requirements of the arrays
  • EMC provides very skillful and high response team in case of any issues in isilon
